BRADSHAW SHEET HANDLING APPARATUS Dec 25, 1962 6 Sheets-Sheet 6 Filed July 29. 1959 INVENTOR. ROBERT S. BRADSHAW ATTORNEY This invention relates generally to sheet and web feeding and handling devices and, more particularly, to apparatus for handling record forms and for feeding the forms to and away from various stations including a data imprinting station. While the invention is capable of a variety of uses in the sheet and web feeding art, it finds special application in bank bookkeeping machines for handling and feeding various forms and documents such as ledger account record cards and continuous form journals, and therefore it will be described hereinafter in connection with such use.

An important object of the invention is to provide an improved apparatus for handling and feeding sheet and web forms in business and other machines.

Another important object of the invention is to provide a novel arrangement and structure for data imprinting machines whereby record forms are delivered expeditiously along dirferent feeding paths both to and from a single imprinting station where data may be printed or otherwise impressed on the forms of the respective paths.

A further important object of the invention is to provide improvements in recording machines whereby large quantities of record material may be inserted into and removed from the machines by the operator in a most convenient and rapid manner with a minimum of manual efiort.

Another important object of the invention is to provide apparatus enabling repeated processing of a group or stack of sheet record forms through a business machine without any manual handling of either the sheet stack or the individual sheets.

Another important object of the invention is to provide in a business machine having an imprinting or data impression receiving position for a record form means for pre-positioning at an advance or ready position individual record forms fed from a supply station so that the pro-positioned or advanced form may be fed to the imprinting position in the shortest possible time.

A further object of the invention is to provide a plurality of record form supply stations with means for feeding a record form from a selected supply station into a feeding path leading to and away from a common imprinting position or data impression receiving position.

Still a further object of the invention is to provide means for withdrawing record forms from the machine as they are passing therethrough and delivering the forms for the attention of the operator.

These and other objects will be more fully revealed in the following detailed description of the preferred embodiment of the invention when read in conjunction with the accompanying drawings in which:

Considered briefly in its broad aspects, the invention comprises apparatus for handling of forms at a supply station and delivery station respectively, means for feeding the forms from a magazine at the supply station to an operating mechanism, and means for further feeding of the forms from the operating mechanism into a magazine at the delivery station. More specifically, the invention contemplates further, the use of sheet and cont-inuous form handling apparatus so constructed and arranged as to provide for feeding of forms of the same or of different physical configurations and from separate supply sources to and away from a common operating mechanism adapted for performing an operation on the forms such, for example, as printing or otherwise impressing data on the forms. The apparatus is contained in a cabinet structure providing for improved operator convenience and visibility of the forms at the operating mechanism and associated with improved loading devices greatly facilitating the handling of forms.

As shown in the drawings, the preferred form of the invention is illustrated in connection with its use in a bank bookkeeping machine for processing record forms such as ledger account record cards and continuous form journal records. Such apparatus comprises an enclosure or cabinet generally indicated at 14 (FIGS. 1 to 3) which is preferably rectangularly shaped as shown, a control unit generally indicated at 15, and a magazine loading platform 16 adjacent to the right side wall 17 of the cabinet 14. The cabinet may include an open frame supporting structure upon which external panels are mounted to form the walls of the cabinet. Devices inside of the cabinet include a principal or main supply magazine 18 (FIG. 4) from which record. sheets such as ledger cards 19 are individually and successively fed to and around a printing platen 20 at a data imprinting station 21 for receiving printing impressions from a printing machine 33 in the forward end portion of the cabinet 14. Each card i9 is separated from the supply magazine 18 by a suitable feeding device 22 and fed into the main or primary document feeding path 23 and advanced therealong to the imprinting station 21. When a card is discharged from the imprinting station 21, it is normally conveyed along the balance of the primary feeding path 23 and finally stacked in a receiving magazine 24.

As is evident in FIGS. 3 and 4, the supply and receiving magazines 18 and 24 are located in the lower portion of cabinet 14 and relatively close together. Referring more particularly to FIG. 4, it is seen that the primary feeding path 23 extends leftwardly from the supply magazine 13 toward the front of the machine and to and around the platen 2.0, thence in a substantially vertical direction toward the top of the machine where it curves to the right, and thence toward the rear of the machine where it curves downwardly and leftwardly to terminate adjacent to the receiving magazine 24 and near its other terminal end and supply magazine 18, thus, in effect, exhibiting a substantially closed loop formation.

The supply and receiving magazines 18 and 24 are preferably similarly constructed and the machine designed for removably positioning the magazines in order that a given supply of record forms or cards 19 may be repeatedly processed through the machine without manual handling of the individual cards simply by interchanging the magazines.

Additional record sheets or ledger cards 19 may be introduced into the machine at the front end thereof, as seen in FIG. 4, from an auxiliary supply bin 25 at an auxiliary supply station 26 or from a manual feeding station 27 positioned just above the supply station 26. The latter two stations are respectively associated with an auxiliary feeding path 28 and an manual feeding path 29 both of which merge with each other and finally merge with the primary feeding path 23 at a position anterior to the imprinting station 21.

Whenever it is desired to withdraw a card 19 from the normal or primary feeding path 23 for the attention of the operator, an auxiliary delivery path Tait-shown at the top of FIG. 4is coupled with the primary feeding path 23 by suitable switching means it to deflect the selected card into the auxiliary delivery path 3i) for feeding therealong into an auxiliary stacking bin 31 preferably located at the front end of the machine.

The primary feeding path 23, auxiliary feeding path 28 and manual feeding path 29 are each provided with similar gate stops G1, G2 and G3 respectively, each of which serves to arrest and detain a card 19 in a ready position in its respective path whenever a previously fed card is stopped in the imprinting station 21. As a card leaves the imprinting station, one of the gate stops is operated to release a detained card for advancing to the imprinting station.

As mentioned previously, the primary feeding path 23 is in the form of a substantially closed loop. Disposed within the loop is suitable structure and apparatus for containing an additional supply of record forms and for feeding the forms to and around the platen 20. As shown in FIG. 4, such structure and apparatus are preferably adapted for feeding and supporting a web-type record form composed of a series of connected documents forming a continuous manifold journal 32 and exhibiting a substantially closed loop formation with a portion thereof passed around the printing platen 20. As so disposed, the journal 32 may receive printing impressions from the printing machine 33 either at the same or at different times as impressions are made on cards 19 fed through the primary feeding path 23, the printing impressions of both the journal 32 and cards 19 being viewable through an opening 34 in the front wall 35 of the cabinet 14. It will be understood that the journal 32 may be a single web for receiving original impressions, or may comprise a plurality of webs for receiving duplicate or carbon copy impressions of the impressions made thereon or on the cards 19. It will further be understood that the journal 32 may be postioned along the platen 20, relative to a card 19, to extend either wholly or partially beyond one side of the card, or beyond both sides of the card if wider than the card, for receiving printing impressions on its side portions separate from those made on the cards 19.

The supply magazine 18 and the receiving magazine 24 are preferably similarly constructed as shown, for interchangeability, with each having a bottom wall 36, four side walls 37 and an open top 38. The cards 19 are deposited or received within the magazines with one of their edges bearing against the bottom wall 36. One side wall 37 of each of the magazines 1% and 24 is formed with a cut-out at 39 for admitting the feeding device 22. into the magazine for feeding cards from a stack therein. The tops of the stacks of cards 19 in the supply magazine 18 and in the auxiliary supply bin 25 are maintained at a predetermined feeding height relative to their respective feeding devices 22 and 40 by suitable elevating mechanism 41 and 42, each shown herein as including a rotatable screw shaft threaded through a nonrotatable but axially movable ledger support and producing linear movement of the support when the shaft is rotated. The support for the supply magazine 18 is in the form of a cradle 43 exhibiting a trough or V-shaped formation for holding the magazine and its ledger content at a canted angle. When the magazine cradle 4-3 is in its lowermost or loading position, it is adjacent to an opening 44 (FIG. 3) in the right side wall 17 of cabinet 14 and in line with a V-shaped track 46 (FIGS. 1 and 13) in the loading platform 16. The receiving magazine 24 is supported on stationary structure 47, which is also trough or ti-shaped, adjacent to a second opening 48 in the side wall 17 and in line with a V-shaped track 49 in the loading platform 16 (FIG. 13).

The transport system comprising the primary feeding path 23, the auxiliary feeding path 28, the manual feeding path 29 and the auxiliary delivery path 3%) is formed of similar structure defining the respective paths and includes transport guides or edge aligning members 5t exhibiting a channel-shaped formation (FIGS. 8 and 10) and a plurality of fixed guide ribs 53 and 54 (FIG. 8). The opposing guide ribs 53 and 54 constitute a chute structure which also may be regarded as including the edge guiding members 50. The edge guiding members 50 are secured to an internal vertical wall 51 adjacent to the left wall 52 of the cabinet. The guide ribs 53 are secured to cross rods 152, each rod having one of its ends fixed to the internal Wall 51 and the other end fixed to an internal frame member of the machine, not shown, adjacent to the right side wall 17 of cabinet 1-4. The guide ribs 54 are similarly secured to cross rods 153 also fixed at their ends to the internal wall 51 and the internal frame member. The guide ribs 53 are slightly spaced from the guide ribs 54 throughout the transport system for freely guiding each ledger card 19 therebetween along the respective feeding paths 23, 28, 29 and 30, as will be explained more fully hereinafter.

Disposed along the feeding paths and adjacent to the internal wall 5?. are two sets or series of pairs of feed rollers 55 and 56 respectively (FIG. 4) adapted for feeding the cards 19 by one of their margins while maintaining the adjacent marginal edge of the cards against the bases (FIG. 8) of channels 50. By engaging the cards near one edge only, cards of various widths can be handled to the transport mechanism without adjustment by the operator. The side of the card feeding path opposite to the rollers and aligning guides is open and unobstructed for ready access by the operator by removal of adjacent wall panels. The rollers 56 are disposed in the respective feeding paths prior to the gate stop positions G1, G2 and G3, and prior to and along the imprinting station 21 while the rollers 55 are positioned after the gate stop positions and after the imprinting station.

Each roller 55a (FIG. 8) of each pair of rollers 55 is fixed on a shaft 57 rotatably mounted in a body 58 secured to an angle bracket 59 fixed to the internal wall 51. Secured on shaft 57 is a gear 60 and slidably keyed on the shaft are friction clutch discs 61 and 62. Between the discs of and 62 and journalled on shaft 57 is a drive pulley 63 having friction clutch discs or facings 64 and 65 secured to its ends and which are maintained in fric' tional contact with the discs 61 and 62, respectively, by means of a pressure cup 66 mounted on the shaft and retained under pressure against the disc 62 by means of a retaining ring 67. Secured on the outer end of shaft 57 is a governor-type shut-off device 63 of similar construction and operation as one disclosed in a copending US. patent application in the name of F. V. Palssciano, Serial No. 816,005, filed May 26, 1959 and assigned to the assignee of the present invention.

Each roller 55b of each pair of rollers 55 is secured on 5 one end of a shaft 69 rotatably mounted in one end a bracket the other end of which is yoked and pivotally secured to the body 58 on a pin 71 (FIG. A gear '72- secured on the other end of shaft 69 is in mesh with the gear 6t? on shaft 57. A tension spring '73 secured to body 58 and bracket 71 urges the bracket in a clockwise direction, as seen in FIG. 5, to urge the roller 55!) towards the roller 5511. A screw 74 threaded through bracket 7d has its end set to stop against a rib 75 of body 58 for adjustably setting the spacing of the rollers to suit the thickness of the particular record form or ledger card it The drive to the pulleys 63 is furnished by scans of belts 76 from a source of power, such as an electric motor or motors M, and transmitted therefrom to one or more other pulleys by means of belts 77 in a manner not shown, but well understood.

The rollers 56a and 56b (FlGS. 5 and 7) of each pair of rollers 56 are similarly rotatably mounted on antifriction hearings on one end of shafts 78 and 79 respectively, and supported adjacent the internal wall 51 by a body and bracket til respectively, similar to those described for rollers The drive for rollers 56 is similar LO the drive for rollers 55 but differs in certain respects in that drive pulleys, not shown, but similar to pulleys 63 are secured on the opposite ends of shafts 73 and friction disc clutches, to be described, are disposed within each roller 56a and 56!; rather than adjacent to pulleys 63 as described for rollers 55'. As seen in FIG. 7, the friction disc clutches are disposed in a counterbore of rollers 56 and comprise friction discs 83 and 8dslidablc on shafts 78 and 79 and friction discs 85 slidably keyed on the shafts by. means of keys 86. Compression springs 37 bias the discs 85, $4 and 83 toward the bottom shoulder 88 of countcrbores 82 to frictionally couple the rollers with their shafts 78 and 79.

As mentioned earlier, the rollers 55 and 5d are adapted to maintain a marginal edge of the cards in alignment against the base of the channels 5t). For such purpose, the roller assemblies (H68. 5, 7 and 8) are secured to the brackets 59 and $9 on an angle in the direction of feed slightly less than 99 to the base of the channels 5i] so that the axes of the rollers form an acute angle a (FIG. 7) therewith.

The gate stops Gi, G2 and G3 (FIG. 4) are similarly constructed so a description of one of them will sulfice. Gate stop G1 comprises a fixed block (MG. 5) having a cam surface 91, a stepped portion 92 and a land 93 disposed along the center line of the primary feeding path A stop member 3 pivotally mounted on a fixed pin 95 comprises an arm from which depends a toe 7 and a second bifurcated arm 93 (see also P16. 6) pivotally connected to one end of an armature 99 of an electromagnet the secured to a fixed bracket lt-tlZ. A compression spring lill between bracket 102. and a shoulder N3 of the armature biases the armature outwardly of the electromagnet when the latter is cle'energized to thereby rock the stop member into the feeding path as seen in PEG. 5, in which position toe 97 is on the stepped portion and the arm 96 spaced from land )5 a distance somewhat greater than the thickness of a card 19.

Returning to FIG. 4, in order to support the continuous record or journal 32 within the primary feeding path loop 23 with a portion of the journal around the platen 21) there is provided fixed structure comprising a pocket 104 for holding the journal supply, a lower track ltlii for supporting the lower run of the journal, an upper track ill-5 for supporting the upper run of the journal, and a receiving pocket 197 for stacking the journal in manifold fashion, as is well known. The journal 32 is line-spaced or driven about the printing platen 2t; by means of a tractor-type pin feed drive N3 of well known construction engaged in marginal apertures in the journal. The pin feed drive ltlti is operated by a mechanism, not shown, and may be responsive to signals from an associated apparatus forming no part of the present invention.

The feeding devices 22 and 40 for separating cards from the supply magazine 13 or the auxiliary supply bin 25 respectively, may be of any well known construction, however, as illustrated, they are preferably of the vacuum wheel type of the class shown in US. Patent No. 939,269.

As cards are fed through the respective feeding paths, as will shortly be explained, they pass between certain ones of reading heads RH and a writing head WH (PEG. 4) and associated pressure plates p for sensing and writing of coded data on the cards for purposes not forming a part of the present invention, however, due to the friction imposed on the cards by the pressure plates and reading and writing heads the friction clutches for the rollers 55 represented by discs 61, 62, 64 and 65 are made sufliciently strong to provide a suitable driving torque for overcoming the friction and feeding the cards past the heads at a predetermined and precise linear velocity. The friction clutches for the rollers 56, however, represented by discs 83, 84 and are made relatively light to enable the rollers 56 to stop instantly when the cards are stopped, as will shortly be explained. It should also be mentioned that While the rollers 55 and 56 are shown in FIG. 4 to be of different diameters, this is only a matter of choice since both sets of rollers are rotated at the same tangential velocity. The rollers 56 are preferably small and lightweight in construction and therefore of low inertia to further enable them to stop instantly, as mentioned above.

In the operation of the apparatus, the rollers 55, 56 and vacuum wheels 22 and 40 are rotating continuously. For feeding a record member or ledger card 19 from the supply magazine 13, vacuum is supplied to the wheel 22 through a hose 169 leading to a valve mechanism and source of vacuum, not shown, and the top card of the stack is fed by the wheel 22 into the primary feeding path loop 23 and between the guide ribs 53 and 54 and with its left side edge riding in the channel St). The rollers 56 engage the card by its left margin and advance it along the primary feeding path 23 while maintaining its left edge against the base of channel 50. If there is no previously fed card in the imprinting station 21, electromagnet fill) at G1 is energized to rock stop member 94 in a clockwise direction, as viewed in FIG. 5, to allow the advancing card to be fed by the rollers into the imprinting station. If the card is to receive printing, it will be stopped in the imprinting station 21 at an appropriate line position by a line selection mechanism generally indicated at and forming no part of the present invention but fully disclosed and claimed in a copending application of Robert S. Bradshaw and Andreas G. Markgraf, Serial No. 838,468, filed September 8, 1959, now matured into US. Patent No. 2,996,166 entitled Record Sheet Feeding and Line Selection Mechanism and assigned to the assignee of the present invention.

If a previously fed card is in the imprinting station 21, electromagnet 1% is allowed to remain de-energized in which case the stop member 94 will be in the position shown in FIG. 5, so that the leading edge of the advancing card Will come against the toe 97 as it passes between the arm 96 and land 93. As the card is thus stopped by toe 97, the rollers 56 will stop instantaneously on the card due to their low inertia and slipping of their disc clutches, while their shafts 73 and 79 continue rotating. As soon as the previously fed card is released and discharged from the imprinting station 21 for delivery to the receiving magazine 24, the electromagnet is energized to release the detailed card to the driving torque of the rollers 56 for advancing into the imprinting station.

The cards are released from the imprinting station 21 by the line selection mechanism lit) in a manner described in the above mentioned Bradshaw and Markgraf application and they are normally fed along the primary feeding path 23 for stacking in the receiving magazine 24-. As seen in FIG. 4, the primary feeding path 23 extends over the inside path for the journal 32 and then curves downwardly and leftwardly around the pocket 107 to terminate ad 'acent to-the receiving magazine 24. When a card is discharged from the primary feeding path 23 at this terminal end, its leading edge will come against a fixed stop 111 and the card will drop down onto an endless are deposited into the receiving magazine in the same that .Izl

order and face position, relative to the cut-out they occupied in the supply magazine so that the supply or stack of cards may be reprocessed the s order through the machine without manual handling L- the cards by interchanging the magazines.

Additional cards may be introduced into the machine from the auxiliary supply bin 25 in a manner similar to that described for feeding cards from the supply 18, that is, by supplying vacuum to the wheel di? and similarly stopping and releasing a card at the gate stop G2. Cards may be introduced into the machine individually by the operator by placing each card on a table top 116 (FIGS. 2 and 4) and sliding the card through an opening 117 in the front wall of cabinet and into the manual feedingpath 29 until it is engaged by the rollers 56 associated with that path. Stopping and releasing of the cards at the gate stop G3 is also accomplished in a manner similar to that described for the primary feeding path 23 each disposed adjacent to a guide rib 53 and its associi.

ated guide rib 54. The rock arms 113 are secured on a common shaft 120 rockably journalled at one end in the 'internal wall 51 and at the other end in a frame member,

not shown, adjacent to the right side wall 1'7 of cabinet 14. Secured at one of its ends on shaft 120 is a lever arm 121 whose other end is connected to a tension spring 122 anchored to a pin 123 fixed to wall 51. Pivotally connected to the medial portion of the lever arm 121 is one end of an armature 124 of an electromagnet 125. In the normal or non-operated position of the rock arms 118, as seen in FIG. 10, their lower surfaces 126 are parallel to the primary feeding path 23 at this position so that cards 19 are normally fed below the rock arms 118 through the channel Stland guide ribs 53 and S4 of the primary feeding path 23 for delivery to the receiving magazine 24.

To switch cards to the auxiliary delivery path 30, electromagnet 125 is energized to rock the arms 11% counterclockwise, as viewed in FIG. 10, until their end portions 127 are disposed below the primary feeding path 23. The cards will then be deflected by curved portions 12.8 of the rock arms 118 from the primary feeding path 23 into the channel and guide ribs 53 and 5d of the auxiliary delivery path 36 and advanced by pairs of op posed forwarding rollers 154 and cooperating pressure rollers 155 and then by the rollers into the auxiliary stacking bin 31 (FIG. 4).

In the present embodiment of the invention, channel 54} of the auxiliary delivery path Call has been chosen to take a relatively sharp bend as at "156 (FIG. 10) and therefore the forwarding rollers 154 and 155 are preferably employed at this region and spaced across the machine to assist the rollers 55 in maintaining the cards 19 in edge alignment around the bend 156. One roller 15 i is adjacent to the internal wall51 and the other rollers 15 i r; are each disposed between-adjacent pairs of guide ribs and 54. The rollers R54- are secured on a powerdriven cross shaft 157 journalled'atone end in the internal wall 'il and operated from motor M by a belt 7s and pulley, not shown, and with its other end journallcd in a frame member, not shown, adjacent to the right side wall 3 .7 of cabinet 14. The rollers 155 are spring pressed against the rollers 15 i and are supported on a cross shaft 158 fixed at one end to the wall 51 and at the other end to the above mentioned frame member.

The apparatus described thus far for feeding and edge guiding the cards 19 through the various feeding paths has proved most reliable in operation and also in preserving the condition of the cards. However, should a card become buckled or otherwise damaged while in the grip of a pair of rollers 55 such as to cause a sufiicient drag or stopping of these rollers, slipping will occur between the clutch discs 61 and 62 and clutch facings M and d5, whereby the reduced angular velocity of the particular shaft 57 will cause its governor-type shut-oif device as t operate a microswitch 129 (FIG. 8) in a manner described in the above mentioned Palasciano application for patent, and thus shut off power to motor M driving the roller driving belts 76.

For handling the stacks of cards, and particularly when the stacks are made up of large quantities of cards of appreciable size and weight, the magazines l8 and 24 are conveyed to and from the loading platform 16 by means of a transport cart generally indicated at 159 (FIGS. 1, 3 and 11) having a magazine supporting shelf 131 of an equal height with the normal surface 132 of the loading platform. An elongated outwardly opening C-shaped channel or rail 1.33 (PEG. 12) is secured to the upper edge portion of the right side wall i3 2 of the loading platform 16 for slidably latching the cart 13d to the platform by means of a latching mechanism constructed as a part of the cart 130. The latching mechanism comprises a latch bar 135 having a cam surface 136 adapted to ride over the lower flange 137 of rail 133. The latch bar 135 is elongated to extend the distance between two of the cart legs 138 and formed with lugs 139 pivotally connected to the legs. At each end of the latch bar 135 is a stop member M0 having a lower extension 141 secured to the bar 135 and a lateral ear 142 pivotally connected to one end of a link 143 whose other end extends to the far side of the cart and is pivotally connected to an arm 144 of a bell crank lever 14-5 pivotally connected at 146 to an angle bracket 147 fixed below the magazine supporting shelf 1'31. A tension spring 143 having one end secured to link 143 and the other end secured to a frame portion 149 of the cart serves to urge the latch mechanism to the latching position shown in HS. 12, in which position an upper extension 159 of the member M ll is stopped against the frame portion 149 thus to limit counterclockwise rocking of the latch bar 135. An elongated rod-shaped handle 151 is secured to the levers at the opposite sides of the cart for manual operation of the latching mechanism. in the latched position, the latch bar 135 is loosely engaged over the flange 137 so that the cart may be moved conveniently along the platform from one end to the other.

Raising of handle 351 will rock the latch bar 135 clockwise for detaching the cart from the loading platform for movement away therefrom. Although only one linkage system including link 14-3, stop member 14% and spring 3148 is shown and described it is understood that a similar mechanism is employed at the other side of the cart. The linkage system provides a remote control enabling the operator to stand on the far side of the cart and attach it to the rail 133 of the platform.

A supply magazine 1% containin cards is slid from the cart shelf 131 onto an adjacent platform surface 132, tilted into the track 46 and slid therealong into the side wall opening 44 of the cabinet ll i until it is nested in the support or cradle 53, the cradle having been moved to its lowermost or loading position for this purpose. The receiving magazine 24 is handled in a similar manner by sliding it along track 49 through the side wall opening 48 until it is nested in the stationary structure or cradle 47.

In connection with the handling of record forms or ledger cards by means of magazines, as described above, it is to be noted that in the use of prior art devices the record forms are first removed from a receptacle before they are fed through a machine. In the present invention, however, the supply magazine containing the record forms or ledger cards is placed in the machine and remains therein throughout the feeding operations. Thus there is eliminated the additional operation of prior devices of removing the stack of record forms from a receptacle prior to feeding.

From the foregoing description it will now be seen that the invention provides improvements in form handling and feeding apparatus and having particular, but not limited, application in bank bookkeeping machines. While there has been disclosed a specific embodiment of the invention, it is to be understood that this is the preferred form and that various modifications and changes in size, shape and arrangement of parts may be resorted to without departing from the true spirit of the invention. Ac-
